High Frequency of Loss of Heterozygosity in Imprinted, Compared with Nonimprinted, Genomic Regions in Follicular Thyroid Carcinomas and Atypical Adenomas

Abstract

Our observations suggest that IRs are more prone to genomic instability in FTCs. The fact that the ATY trended toward differential IR/NIR LOH, similar to FTC, may suggest that loss of IR might be instrumental in the adenoma-carcinoma sequence in thyroid carcinogenesis and that ATY could be an important intermediate in this pathway.
